| 5680514 | Multiple elastic feature net and method for target deghosting and tracking A multiple elastic feature network having N independent sets of M feature specific neurons that respond to the temporal properties of a number of targets. The targets are represented by sets of M feature specific coordinates. Each of the neurons and its c... | 10/21/1997 |
| 5668442 | Plasma-assisted tube with helical slow-wave structure Microwave amplifiers are disclosed having a hollow helix slow-wave structure coupled directly to input and output waveguides. This helix-waveguide coupling structure couples the TEM mode of the helix to the TE10 mode of the rectangular waveguides and also... | 09/16/1997 |
| 5665614 | Method for making fully self-aligned submicron heterojunction bipolar transistor A submicron emitter heterojunction bipolar transistor and a method for fabricating the same is disclosed. The fabrication process includes lattice matched growth of subcollector, collector, base, emitter, and emitter cap layers in sequential order on a se... | 09/09/1997 |
| 5665253 | Method of manufacturing single-wafer tunneling sensor A tunneling tip sensor and a method of photolithographically fabricating a unitary structure sensor on a semiconductor substrate are disclosed. A cantilever electrode is formed on the substrate with one end suspended above the substrate at a distance from... | 09/09/1997 |
| 5663694 | Triggered-plasma microwave switch and method A microwave switch selectively directs a microwave signal along first and second signal paths. The switch includes a microwave transmission member, a microwave chamber formed by the transmission member for containing an ionizable gas, input and output por... | 09/02/1997 |
| 5652596 | Scanned antenna system and method A compact scanned antenna which includes a radiator, a rotatable tube and a line source. The radiator is formed by plating a shaped dielectric core. It generates an antenna beam at an output aperture in response to a microwave signal at an input port. The... | 07/29/1997 |
| 5652444 | Structure and method for making FETs and HEMTs insensitive to hydrogen gas A structure and method for making HEMTs with a gate metal having a layer comprising titanium, a layer comprising vanadium over the layer comprising titanium, and a layer comprising gold over the layer comprising vanadium. Such HEMTs are insensitive to hyd... | 07/29/1997 |
| 5650835 | Reconfigurable optical beam splitter and method A reconfigurable optical beam splitter and method establishes replicated periods of optical phase shift regions across a liquid crystal cell to form an optical grating in the liquid crystal. A non-linear pattern of phase shift regions is established withi... | 07/22/1997 |
| 5650787 | Scanning antenna with solid rotating anisotropic core A scanning array antenna employs a solid rotating core having an anisotropic refractive index within an apertured waveguide that emits radiation in response to an input beam propagating through the waveguide. Rotating the core changes its refractive index... | 07/22/1997 |
